11. Conformational Studies of Biologically Active Peptides
Abstract : In this work conformational studies have been performed on peptides from four different systems in an attempt to gain knowledge about their biological function. Circular dichroism (CD) spectroscopy and nuclear magnetic resonance (NMR) spectroscopy in combination with distance geometry and restrained molecular dynamics simulations were the methods used.

12. Synthesis, conformational analysis, and biological evaluation of peptides from E. coli P pilus proteins
Abstract : Many bacteria utilize hairlike protein appendages (pili) to attach themselves to mucosal cell surfaces in the host organism. The pilus is assembled from protein subunits synthesized inside the bacteria and transported to the outer cell wall for incorporation into the growing pilus. READ MORE

13. Pneumococcal pili and other cell surface properties affect the infection biology of Streptococcus pneumoniae
Abstract : The pneumococcus, Streptococcus pneumoniae, is a major respiratory tract disease causing pathogen with an estimated mortality of 1-2 million per year worldwide. It is the most common bacterial cause of sinusitis, otitis media and community acquired pneumonia and also a major cause of invasive diseases such as septicaemia and meningitis. READ MORE

14. Virulence Factors and Motility Mechanisms of Pathogenic Neisseria
Abstract : Neisseria gonorrhoeae and Neisseria meningitidis are two closely related human specific pathogens. Neisseria gonorrhoeae is the causative agent for the sexually transmitted disease gonorrhea and often causes asymptomatic infections in women which is a cause of infertility. READ MORE

15. Pathogenic Neisseria : Single cell motility, multicellular dynamics and antimicrobial susceptibility
Abstract : Neisseria meningitidis and Neisseria gonorrhoeae can colonize humans without causing any symptoms. However, gonorrhea and invasive meningococcal disease are serious health concerns. An essential virulence factor for neisserial adhesion to host cells, twitching motility and microcolony formation/aggregation is the retractile type IV pili (Tfp). READ MORE
